Benefits of technology

Ensures accurate alignment and high stability of protective bars, preventing damage and maintaining effective protection during vehicle maneuvers and accidents, while accommodating various vehicle geometries and tolerances.

Problems solved by technology

However, after the restraint system is secured to at least one of the pillars, even slight twisting of the pillars leads to large errors in alignment of the at least one protective bar.
In extreme cases, these errors in alignment may have the result that the at least one protective bar protrudes so far to the side out of the vehicle that said protective bar may become damaged during manoeuvring.
Alternatively, when twisted in the opposing direction the protective bar may also considerably limit the freedom of movement of the driver.

Embodiment Construction

[0016]The only FIGURE shows a three-dimensional view of a detail of an industrial truck 1, substantially only one pillar 2 thereof being visible. Two brackets 3, 3′ are secured to this pillar 2 by means of screws 4. As an alternative to the screws 4, the bracket 3 may also be configured as a clamp so as to avoid in this manner drilling into the pillar 2. This may be significant, in particular, in the case of pillars 2 which are configured to be thin. A support 5 which bears a pivotable protective bar 6 is supported on the bracket 3.

[0017]Moreover, a slot 7 is provided in the bracket 3, an eccentric 8 engaging in said slot. This eccentric 8 is supported on a threaded bore 9 of the pillar 2. By rotating the eccentric 8 an eccentric head 10 produces a rotational movement which is transmitted to the slot 7. The vertical component of this rotational movement is eliminated in this case by the slot 7 and only the horizontal movement component is transmitted to the bracket 3. In this manner...

Abstract

A restraint system for a driver of a vehicle comprises at least one protective bar (6), being supported on at least one pillar (2). To achieve an alignment, at least one protective bar (6) is pivotably supported by at least one eccentric (8). The protective bar is lockable.

Description

[0001]The present application claims priority to German Utility model application no: DE 20 2017 005 064.1, filed Sep. 28, 2017.FIELD OF THE INVENTION[0002]The invention relates to a restraint system for a driver of a vehicle, in particular of an industrial truck. Said restraint system comprises at least one protective bar which is supported on at least one pillar of the vehicle.DESCRIPTION OF THE PRIOR ART[0003]A generic restraint system is disclosed in EP 50106605-B. Said restraint system comprises a protective bar which is supported on a rear pillar of an industrial truck. Said protective bar is pivotable between a substantially horizontal restraint position and a substantially vertical released position in order to permit, on the one hand, a secure restraining action and, on the other hand, easy climbing in and / or out of the vehicle. In practice, this restraint system has been repeatedly proved to be expedient and forms the starting point of the present invention.[0004]The objec...
